You could have a global JS variable. On each click, you add 1 by using a function that is attached to the button. If you link your code, we can check on it.

1. Assign a class, id or data-attribute to your button and the element which includes your counter. Something like this: <p id="counterValue">Counter: 0</p> <button id="counterButton"> 2. Go to Javascript and store your html elements in variables: let button = document.getElementById("counterButton"); let counterElement = document.getElementById("counterValue") 3. assign an initial value of your counter to a variable so we can increment that every time you click the button: let counter = 0; 4. Now we need a Event Listener which listens to the button and triggers every time we click on the button: button.addEventListener("click", () => { counter++; counterElement.innerHTML = "Counter: " + counter; } counter++ means that we add +1 everytime we click on the button. counterElement.innerHTML replaces the content of your <p> with "Counter: " and the new Value. Note: Don't use click events inside your html like: onclick="functionName". It is bad practice in Software developing. Always seperate your stylesheet and script. In Software developing we call this "Separation of Concerns". This helps to keep your code clean and clear
